Primers Pedestrian Traffic Coatings - Sikalastic® EP Primer/Sealer

Two-component, Universal Primer.

Sikalastic® EP Primer/Sealer consists of two components: an epoxy resin (Part A), and an activator (Part B). In its wet mixed state, it is red in color.

• Low odor, low VOC formulation
• Compatible with most common substrate and flashing materials
• Corrosion protection in industrial and marine environments
• Enhances adhesion to a broad range of metallic substrates
• Protects against migration of volatile bitumen or plasticizers
• Easy application by brush or roller

Usage

Versatile primer for use with:

• Sikalastic® RoofPRO Systems
• Sikalastic® DeckPRO Systems

Suitable for use on most sound substrate surfaces where both a penetrative and surface-lying effect is required.

Coverage

Coverage:

250 ft²/gal. on non-absorbent smooth substrates.
200 ft²/gal. on prepared, dry concrete.
75-100 ft²/gal. on mineral surfaced modified bitumen.

Note: Rough, porous, or absorbent surfaces will require additional primer and will reduce yield.

Application Steps

SUBSTRATE PREPARATION

All substrate surfaces shall be clean, dry and sound. Acceptable substrates include: sound concrete and masonry, wood and plywood, modified bitumen membrane, mineralized asphaltic cap sheet, asphalt and asphalt mastic, ferrous metals, galvanized, lead, copper, aluminum, brass, and stainless steel. Reference separate System Data Sheet for specific surface preparation requirements.

MIXING

Mix ratio is 3:1 (A:B) by weight and volume. PREMIX PART A BEFORE MIXING PARTS A & B TOGETHER. Add Part B into Part A and mix with a mechanical mixer (Jiffy) at low speed. Avoid adding air into the primer during mixing. When fully mixed, the primer should be free from streaks and of a uniform red color. Do not break down kits into smaller quantities.

APPLICATION

Apply by brush or phenolic resin core roller at the recommended rate. Correct amount of primer will saturate the substrate and leave a slight film on the substrate top surface. Apply evenly without puddling.

CLEANING OF TOOLS

Remove wet primer with MEK, xylene, or oxygenated solvents. Once cured, primer can only be removed by
mechanical means. Strictly follow solvent manufacturer’s warnings and instructions for use.
